How Long Does Spray Paint Take To Dry?

Spray paint is a great material for touching up metalwork, creating street-art style pieces, and other artistic applications. There is often the assumption that spray paint will dry really quickly because it is such a fine application. But, there is then the risk of not waiting long enough and ruining the piece. So, how long does spray paint take to dry and what else should you consider when using spray paint at home?

How Long Does It Take For Spray Paint To Dry?

Unfortunately, there is no simple answer to how long it takes for spray paint to dry. That is because there are so many different factors at work. The drying time will depend on the thickness of the coats, atmospheric influences, and the type of paint used. You also need to be sure that each coat is completely dry before reapplying for the best results.

What Type Of Spray Paint Are You Using?

The drying time of spray paint is mostly down to environmental conditions and application methods, as seen below. But, the product may play its part. Some spray paints are faster drying than others. You can look out for options with “quick-dry” or “rapid” in their name. It also helps to check user reviews to see if the claims are accurate. Some top brands claim that you only need to wait eight minutes or less between coats and it is important to follow their instructions for the best results. This could be the case, but don’t just take their word for it. Check your paint before reapplying and be cautious where necessary. If 10 or 15 minutes is more realistic then wait.

What Are The Conditions Like Where You Are Working?

The atmospheric conditions of the space will play a big part when it comes to the drying time. For example, artists spraying canvases in large studios or people in workshops may find that it takes longer because of humidity levels or a lack of ventilation. Ventilation is essential when working with spray paint to make sure that you aren’t dealing with too many harmful fumes. The alternative option is to spray outdoors where the fresh air will make things a little safer and more pleasant. Still, there is a humidity risk out here if the air is a little damp. Work with the weather where possible and make the most of the sunshine.

What Happens If You Don’t Leave Spray Paint To Dry Long Enough?

Some people in a rush to finish a project, or just impatient to get the job done, may decide to chance it and put the next coat of paint on. However, this could prove costly when the first coat isn’t dry. You might find that the second coat doesn’t adhere properly, that you end up with streaks and other imperfections, and that you increase the overall drying time. It does save time to wait until each coat is dry.

How Can You Tell If A Coat Of Spray Paint Is Completely Dry Or Not?

One way to tell if your paint is completely dry is to see how it feels. If it is still a little wet to the touch then it is best to wait a little longer. You may also be able to tell by eye if you don’t want to touch it, but this can be risky. Touch the paint in an area where fingerprints won’t show up so badly.

You may also find that the paint feels tacky to the touch for a while after painting. This could be a sign that the layers underneath the topcoat weren’t dry enough and the surface is struggling to cure. It is best to leave it for a while until the paint is fully dry before using the object. Otherwise, you could cause damage.

How Can You Make Spray Paint Dry Faster?

There are different ways that you can speed up the process and ensure that your coats are dry enough to continue working. As mentioned before, conditions are important so try and work outside on a sunny day. If that isn’t possible and you need to work in a studio for the afternoon, bring in a heater and try and improve air circulation as best you can.

Another top tip is to work in thinner coats. You may end up using more coats than you intended to at first, but this can pay off in the long run. Start with a thin coverage across the surface, give it ample time to dry in those aforementioned conditions, test it in the right spot, and go again. The thinner the coat, the more likely it is to dry out in contact with the air and heat. Build up the layers this way until you are happy with the way things look.

Can You Use A Hairdryer To Dry Spray Paint?

There is potential here for faster results because you are using direct heat on a wet surface. Hairdryers are also nice accessible devices you can use in a studio to cut time. However, there are risks because of the way that the high heat becomes concentrated in one area. It is better to use a heat source to control the room temperature than to target areas of paint. Concentrated heat could lead to damage and inconsistencies in the finish. If you do choose to use a hairdryer, keep it moving across the surface and don’t get too close.

How Long Does It Take For Spray Paint To Dry?

In short, the answer here is that it will take as long as it takes. Some projects may dry really quickly in a dry and ventilated area when using thin coats and high-quality paint. Others may take longer depending on the application method, conditions, and product. The most important thing to remember is that you can’t rush the process. It is far better to walk away and do something else – leaving the artwork or item in a safe place – and come back later.
